I'm the secretary for my university Chess Club. I need to be able to send emails to ~70 people about once or twice a week (possibly with attachments and using BCC).
I have set up a Gmail account for this purpose. However, it thinks I'm sending spam so is blocking the emails. Looking at the Google guidelines, it seems that I should make a Google Group. However, that would require people to signup for a Google Account and then sign up to the Google Group.
I need a simple and free way to send mass emails to everyone who is on the Chess Club email list. Can I do this with Gmail? What is the best option?
